Hi Moran. I see it is now offline, with the last readings showing the low voltage. I suspect one of the high voltage caps / diodes might have failed. In some other situations, the inductor is the culprit or the MPSA42 transistor.

The A2 unit 41000008 was shipped to the lucky winner . Again, congrats ecloud!

@Outsider, this competition was without any voting, the participation only implied posting at least a photo with your KIT1 units. But thanks for the idea, for the next one, we should vote for the best construction!

Merry Christmas all and/or Happy Holidays!

I was pleased to see some beautiful KIT1 constructions here, both on factory PCBs and DIY. This thread encouraged the development, and now we have a full open-source KIT1 on github, thanks to Akos and all of you.

Tomorrow evening I’ll select the winner of the A2 unit, randomly, from the list of those of you that posted their KIT1 units here on the blog.

For the lucky winner I’ll need a shipping address and a contact phone number so I can ship it on Friday.

Good luck to all of you!

As said, it was a “competition, for all those that post their construction here. We’ll have some voting in place, and the nicest build wins a model A2 detector. DIY units go as well.”

For those that didn’t join this, there is still time to post pics with the KIT1 until tomorrow 6pm GMT+2 .
